2 Claims.

This invention relates to paper cones designed for use as cores forthread packages in the textile industry, and its general object is toprovide a cone that is perfectly balanced and round throughout theentirecircumference thereof,and has a uniform outer surface free fromthe objectionable longitudinal ridge seam present on' cones now ingeneral use. f

A further object -is to provide a cone constructed from several conicalshells that has its apex end colored for identification purposes, eitherby using a colored hard drying material or by providing openings in theouter shell and disy moved from the sheet.

posing a lining of contrasting color between the inner and outer shellsto show through the openings.

Another object is to providey a cone for the purpose set forth, that issimple in constructionl l' panying Adrawings and specifically pointedout in the appended claims.

I n describing the invention in detail, reference will 'f be' had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which:

Figures 1, 2 and 3 are plan views of one of the forms of the disksegments used in producing my cone.

Figure 4 is a longitudinal sectional view taken through the shaping andpressing apparatus.

Figure 5 is a-view of the outer or female die of the apparatus.

Figure 6 is a view'of the inner orI male die.

Figure 7 is a sectional view taken through the base member of theapparatus. Figure 8 is a transverse sectional view taken through theapparatus in its entirety with a cone therein. l i

Figure 9 is a view of the segments of Figures 1 to 3, rolled in conicalshell formation and illustrates the manner of mounting'the same, so thatthe seams are disposed out of registration.

Figure 10 is a view of a shell providedwith a modified or locking seam.I

Figure 11 is a fragmentary view ofa shell provided with an overlappingjoint or seam.`

I Figure 17 is a view of a slightly modified form of segment.

Referring to the drawings in detail, and particularly to Figure 15, thereference numeral l indicates a. sheet of paper stock that may or maynot` have a roughened or serrated surface and which is stamped or cut toprovide segment blanks 2 from which my cone is made, the segments beingfirst removed and may be retained in their original shape as shown inFigure 16, or may have a tip of the apex cut away in arcuate formation,as at 3 in the form of Figure 17 or a larger portion of the apex may becut away in arcuate formation as at 4,`in the form of Figures 1 to 3inclusive.

In any event, each segment is rolled upon itself in conical formation asshown in Figure 9 to provideV shells 5. Two or more of these shells withthe longitudinal edges of each disposed in abutting Contact, are nestedone within the other, as likewise shown in Figure 9, and the outer facesof the inner shells are coated with any suitable adhesive material, suchas liquid or plastic cement for securing the shells in face to facerelation to produce a cone of several layers of material, to render thesame sufficiently rigid to prevent any possibility of damage thereto..

When the shells are nested, the seams which are indicated by thereference numeral 6 'are disposed out of registration with each other,as clearly sh'own in Figure 9, and the shells are pressed in nestedformation, as well as shaped to provide a complete co're for the threadpackage, b y the apparatus shown in Figures 4 to 8 inclusive.

While all the shells are originally of the same size, as they are cutfrom the sheet as shown in Figure 15, it will be obvious that the innershells must be slightly reduced in size in order for the shells tosnugly t one within the other, particularly if the longitudinal edges ofthe inner shells are disposed inabutting contact, as shown, and which isof course desirable, so that the inner face of the cone will be uniformand`free from a seamridge like thel outer face, as the longitudinaledges of the outer shell must be disposed in abutting contact, becausesuch is one of the most important features of my cone to meet theexing-inserted in the femalev die.'

` eluded inthe apparatus and xed in the groove is the large end of atruncated conical hollow inner or male die II that is perforatedthroughout the entire area thereof to allow for the passage of airtherethrough to breaka vacuuxnthat may exist during the use of theapparatus.

The latching means shown includesarms I4 having one of their 'e'nds pivoted to one section and extendingfrom the other section 'are studs I5 arranged in the path of openingsinthe free ends of the arms to be received therein for latching thesections together, as clearly shown `in Figure 8.

In the use of vmy apparatus, .I want it understood that the blanks-2 areindividually or lcollectively applied within the outer or female die I2and it wiii be obvious that the blanks wh'esbeing -inserted therein willconform to the conical formation thereof. The sheet I of paper stockfrom which the blanks are cut, may have a coating of adhesive materialthereon, that is retained on the blanks when they are cut rorn the sheetLand inthat event the adhesi ely coated face of the blanks are moistenedprior to or while be- However, the blanks may not have a coating ofadhesive material thereon, and then liquidcen'ient or plastic must beapplied thereto, as will be apparent. It'

will of course be understood that the blanks are inserted with theirsmall ends innermost, and by following the shape of the female die, theyare converted into the shells of my cone. The apex -4 as includingconcentrieally to theopposite end of the cone.

that the cone will beperfectly balanced, a feature wlieci'h is ofimportance in a cone of `this charac l The shell I8 of the form ofFigure 10 is shown a lock Joint, in that one longitudfnal edge thereofhas formed thereon tongues I1 to bereceived in recessesin theoppositelongitudinal edge, but in any event theedges are disposed in abuttingrelation and the same is true withrespect to the tongues and recesses.It will be noted that the tongues I1 increase in width from theirconnection with their longitudinal edge for fitting association with therecesses, so as to prevent any possibility of the tongues being pulledfrom the recesses, thusV the edges' are firmly locked together, and Iwant it understood that the tongues. and recessescan be of other shapesfrom that shown. It will be further understood that the shells of Figure10 are disposedin nested relation and secured accordingly in the '.samemanner as the shells /toprov'ide a cone.

- In Figures 11 and l2', I. have illustrated a shell which fordistinction isiindicatedyby the rei'-l erence numeral I8, as having an'overlapping `ioint I9, or in other words the longitudinal edgesof theshell I8 are cut in rightV angle formation to .providefianges fordisposal in overlapping relaition with respect to each other, as clearlyshown the shells may be skivedWitl 'i-the\skived edges disposed inoverlapped relation. However, it will be understood that regardless ofthe type of Joint used theshells of these forms are adhesively securedtogether in exactly the saine manner as the other shells, for disposalin nested formation to provides completed cone, asbest shown in Figure.s

It has beempreviousiy set forth, that it is necessary for the outersurface of the apex e ds of cones of this character, to .be smooth, inorriier to' prevent damage to the thread, and while the smooth, Ilikewise may use ends er the shells are disposed within the recess 9,and pressure is appliedto'the head plate I0 for forcing the shellstogether and the apex ends thereof within the recess 9 to follow theshape of the latter, as will be obvious upon inspection of Figure 4. Thedies may `be heated, to expedite the drying action of the adhesivematerial be` tween the shells, as well as the shaping action of therounded apex end thereof. Again, in the event the shells are made. frompaper having smooth faces, the inner surface of the die I2 and the outersurface of the die' II may be serrated from adjacent the apex endsthereof to its opf i posite end to produce inner and outer roughenedsurfaces on the cone. However, the apex end portion of the ,die I2 issmooth so that it will produce a smooth apex portion on the cone,especially in the event the cone is made from paper having a roughenedface. upright 8 not only cooperates with the curvature of the recess 9to curve the apex end of the cone inwardly but centers the opening atthe apex end that the advantagesand It will be obviousthat the "and'arrangement of the 'light coat of transparent hard apparatus will renderthe apex end ofthe cone l A l ja hard drying material, such as enamel orthe like and the material is preferably of-a contrasting color thanthatof the cone, for identification purposes. However, any coloringmatter may be used and thence a applied over the coloring matter.

In Figures 13 and 14, I have illustrated a cone provided withidentification means, and for thatpurpose, the outer shell has aplurality ofopenings 20 arranged in rows about the circumferencethereofy adjacent to its apex end, 'the openings being of diamond shapeifi` the form shown, but it will be obvious that they may beof any aplpropriate shape. The intermediate shell may be of a diiferentcolor thanthe outer shell, so that I it can be readily seen through the 'openings20. However, I have shown a lining strip 2|v between the intermediateand outer,shells, and the'stripr is ofcourse of a different color 'thanthat of the outer shell, so that it likewise can be`readily seen throughthe openings 20 for purposes, as will be apparent.

It is thought from the foregoing description novel features` oftheinvention will be readily apparent. l

It is to be'understoodythfat changes may be made in the construction.and in the combination several parts, provided identification that suchchangesfall appended claims.
